DISCHARGING coNvEYERfl Application filed May 5, 1921. Serial No. 467,l )34.

- Be it known that I, JOHN. Ross, acitizen of theUnited States, and residentiof Philadelphia, county of Philadelphia, and-State ofPennsylvania, have invented an Improvement in Dischargingflonveyers, of which the following is a specification.

The object of my invention is to provide a construction of discharging conveyer, especially suitable for useinwrecking buildings or dischargjn-gbricks or other refuse, such as plaster, from high elevations in the building to the vehicle in the street intended to receive the same. 1

My object is more. specifically to so construct theconveyer that it may be placed the nature of which will be morefullyunin a vertical position close up against the side of the building and provide a conduit or passage which, while permitting the downward travel of the material, by gravity, will-retard the same to prevent too rapid a descent,-and whereby. the reception of the material at the lower end of the conveyer is assured at sucha speed that it may be conveniently transferred to the carts orvehicles whichare to convey it to the dumping ground I I My object is fu rther,.to provide the con- Veyer infsectionswhich are capable of'being bolted or otherwise secured together and in that manner conveniently erected in position against the wall of the building or other structure, the sectional.construction adapting the coiiveyer to. be made of any height desired to suit the requirement of the build ing;.the said sections being of such nature, that the speed of travel of the waste mate rial substantially uniform for all vertical heights of the'conveyer. p

lVith the above and. other objects in view,

v derstood from the description hereinafter,

theinvention consists in the novel construction of discharging conveyer, as hereinafter more fully clescribecl and defined in. the

claims.

, Referring to the' drawings; Fig.1 is a side'elevatibn (with the extreme upper end in section), llustrat ng a discharging conduit embodying my invention; Fig. 2 is a perspective view of two sections of the con- "duit, illustrating the general construction and mode of connecting the said sections;

"and Fig. 3 is a Vertical section through the lowermost section of the conduit but reversed n position to what is shown in Fig. 1.

f2 representsthe vertical conduit structure as a whole and is provided at the extreme top with a large hopper 4t having upwardly extending sides into which the brick or plaster is dumped from-wheel barrows or other means, and adjacent to thelower part of this hopper dis an iron grating 5 which may be of any suitable construction and with interstices sufficiently large in area to permit whole bricks to pass through, but to restrict the too suddenfalling of the material on to the interior construction of. the

.conveyer below the hopper. At the bottom ofthe conveyer, the discharging orifice is provided with a sliding or other suitable valve device 6 which is guided at the sides in grooved guides 18. This VHlVB'ClQVlCG or gatet is moved (for controlling the discharging orifice) by. means of a lever 15 hinged on a cross bar 16, and connected by a link 17 with the rear end of the valve or gate device 6 by a hinge joint 19. Any other suitable means for operating the valve or gate maybe employed and any other suitable means for controlling the discharging orifice ofthe conveyer. may be substituted for the same purpose, if so desired, as I do i the discharging conveyer, the same'is composed of a large number of box-like sections 3 whose body'portions may be made of sheet metal as shown, or of wood,'if so desired, as I do not restrict myself in th s respect. As shown, these sections are made upward,

with the rectangular bodies of sheet metal liaving angle iron frames riveted at top and bottom to provide flanges 9. through which bolts 10 may be passed for temporarily bolting these sections .together in vertical y I Each of the sections has within its body an I oblique .fioorlZextending from one wall obliquely .alinem e'nt, as will be clearly understood by 1 reference to Figs. 1 and 2.

downward and terminating near. the. lower floor 12 may be reinforced with channel orother angled iron shape 14. Preferably, the upper endof the floor 12 begins at a. short distance below the upper plane of the body of the section, so as to provide a short drop for the material from the floor of the section above. As will be understood from the drawings, the floors in the successive sections are reversed, which is equivalent to turning every other section half way around beforev bolting them together; In this way, the floors 12 are alterna-tely inclined in opposite directions and provide, in effect, a zigzag passage from top to bottom of the converer. The positions of, these floors are indicated in dotted lines in Fig. 1, and are also clearly indicated in Figs. 2- and 3, but the opposite inclination of the floors in the successive sections, while not definitely shown in Fig. 2, is indicated by the alinement of the rivets which hold the inclined angle flanges 11 of the lower section when comparing it with the upper section. By the use of these sectional portions of the conveyer, the height of the conveyer may be extended to anything desired; and because I the vertical height of these sections is not excessive, the erection of the conduit is a simple matter. Of course, in practice, the conduit would be secured to the building in any convenientlmanner, and as such securing or means of attaching forms no part of my invention, no details in this respect are shown.

It is manifest, that, if desired, the sections may be made of double height and each contain two of the inclined floors 12 and respectively inclined in opposite direction, and which would constitute, in effect, what is shown in Fig. 2. Of course, it will be understood that in such case, it would not be necessary to have the intermediate flanges 9 and bolts 10, as the entire body plates could be of double height.

It will now be understood that when the material is dumped into the hopper 4, and finds its way through the grating 5, it will travel down the successive inclined floors 12, reversing its direction of movement as it passes from floor to floor. This'action will retard the speed oftravel of the material and consequently will remove any severe blows, such as would occur if the material fell directly through a straight conduit; and

material furthermore, when the material reaches the bottom of thezigzag passage, it may be discharged through the chute in an orderly manner and without an excessive quantity of dust, as a pulverizing effect of the material upon itself will be greatly reduced. When the discharge of the material into the chute is to be cutoff, as when changing the wagons or vehicles 8, the gate or valve 6 is moved into position to close the orifice of the lowermost section. The incline of the floors 12 should be sufficient to insure automatic feeding of the material downward by gravity, so that if it should be checked at the bottom by the closing of the valve 6, the mere opening of the valve will insure the continuance of the discharge.

As there is always possibility of large portions of the material becoming jammed or wedged in passing throughthe'sections and as provision must be made to release the material under such conditions, should they occur, I provide one wall of each section with an aperture 22 over which a door 23 pivoted at 24 may be loosely hung. These doors are clearly shown in Fig. 2. In case of such amming of the material, it is only necessary to use an iron rod thrust through the aperture 22 to liberate the material.

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable, and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that I do not restrict myself to the details, as the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is 2- 1. In an apparatus of the 'character stated, an upright rigid self-supporting ranged at intervals from top to bottom and providing a zigzag passagewayin which the bottom of any oblique floor is above the top of the next lower oblique floor, the upper end of the tubular conduit immediately above the uppermost oblique floor provided with a normally open hopper-likestructure for at all times receiving the material to behandled, and the bottom of the upright tubular conduit provided with a discharging orifice having controlling means for regulating the discharge, the said conduit divided into separable sections detachably connected one above the other and each section having one of the oblique floors extending part way across the passageway therethrough and providing a throat at the bottom.

2. The invention according to claim 1, in which there is further provided abj acent to the lower part of the hopper and above the oblique floors, an iron grating sizes of the material to be delivered to the zigzag passageway and to retard the speed of descent of the material from the hopper to the said zigzag passageway.

3. In an apparatus of the character stated,

an upright tubular conduit having its in terior provided with oblique oppositely projecting floors arranged at intervals from top to bottom and providing a zigzag passageway, the upper end of the tubular conduit provided with a hopper-like structure for receiving the material to be handled, and the bottom of the upright tubular conduit provided with a discharging orifice having con trolling means for regulating the discharge, the said conduit divided into separable sections detachably connected one above the other and each section having one of the oblique floors extending part way across the passageway therethrough and providing a throat at the bottom, and in which further the oblique floors are made of wood and have their lower ends reinforced with metal, said i to limit the the respective sections.

4;. A section adapted to form a unit of an upright tubular conduit consisting of a rectangular body having flange portions at top and bottom, and an interior oblique floor extending from near the upper plane of the section and terminating adjacent to the lower plane of the section and extending only, part way across the interior to provide a discharg orifice at the bottom, and wherein the oblique floor is made detachable and is reinforced with metal at its lower end.

/ 5. A section adapted to form a unit of an upright tubular conduit consisting of a rectangular body having flange portions at top and bottom, and an interior oblique floor extending from near the upper plane of the section and terminating adjacent to the lower plane of the section and extending only part way across the interior to provide a dis- 1 chargeorifice at the'bottom in which there is provided a small aperture in the side of the body of the section, intermediate of the top and bottom flanges, said aperture provided with a pivoted closure.

In" testimony of which invention I hereunto'set my hand.
